    Introduction. In 2004, Andre and Konstantin introduced a practical demonstration of graphene (G) synthesis [].Their success has confirmed that graphene exists in a 2D honeycomb-type lattice structure constituted of a single sheet of sp 2-bonded carbon atoms.It is a milestone that first provided solid evidence to support the long-existing graphene theory, which can be traced back to 1947 [4, 5].
